ARKK is trading at $81.62 (-3.38%) as hotter-than-expected September CPI revived higher-for-longer rate fears, an unfavorable backdrop for growth stocks. - On October 14, Treasury yields initially rose, and tech shares led the broader market lower. - Weakness extended into October 15 as global technology and AI-related stocks sold off amid borrowing-cost worries and doubts about AI investment sentiment. ARKK’s growth orientation is a plausible driver; reporting does not identify a specific holding as the cause.
